Abstract

The invention discloses an intelligent optimization method and system for ecological operation of cascade hydropower stations, belonging to the technical field of efficient utilization of water resources and optimal operation of hydropower systems. The method comprises the following steps: establishing a cascade hydropower station reservoir operation model which takes the minimum ecological watershortage as an objective function and considers a complex constraint set; Knowledge rules are used to dynamically generate the initial scheduling process, and the initial population is generated by random disturbance in its neighborhood. All individuals are modified to feasible search space in turn, individual fitness value is calculated by penalty function method, individual position and velocityare updated dynamically, and neighborhood search is carried out by adaptive mutation strategy. The search process described above is repeated until the termination condition is met. The invention hasthe advantages of clear and simple principle, fast convergence speed and the like, and the obtained result is reasonable and feasible, and can provide strong technical support for rational allocationof hydropower resources.

Description

technical field [0001] The invention belongs to the field of efficient utilization of water resources and optimal scheduling of hydropower systems, and more specifically relates to an intelligent optimization method and system for ecological scheduling of cascade hydropower station reservoirs. Background technique [0002] On the one hand, the large-scale operation of cascade hydropower stations can greatly improve the efficiency of water energy utilization in the basin and produce significant economic benefits. On the other hand, it will inevitably affect the original shape of the river and destroy the balance of the basin's ecosystem. by figure 1 As an example, it can be seen that the discharge of the reservoir in May exceeded the maximum ecological flow requirement, and at this time too much water would easily lead to river inundation losses; in August, the discharge flow was lower than the minimum ecological flow requirement, and the insufficient water at this time would...
